Cost Saving and Investment Protection. The DVG-5004S/DVG5008S gateways provide an easy and inexpensive upgrade to Internet telephony while allowing users to retain their existing telephone and fax equipment. They protect and extend users' past investments in telephones, conference speakerphones and fax machines, as well as to control their migration to IP with a very affordable and incremental investment.

4 or 8 Internet Telephone Connections. The DVG-5004S provides 4 FXS ports, while the DVG-5008S provides 8 FXS ports for simultaneous Internet phone connections. Plug in regular phone sets to these ports, and they instantly become Internet telephones. For businesses with frequent needs for long-distance and international phone calls, these devices provide great cost savings and convenience, while keeping configuration and maintenance to a minimal level.

Guaranteed Voice Quality. These gateways deliver clear voice and reliable phone/fax communication through implementation of internationally recognized standards for voice and data networking. They incorporate Quality of Service (QoS) functions to ensure that voice received through the Internet is the same as or even surpasses that received on the ordinary phone.

Convenient Call Features. The DVG-5004S/DVG5008S support extensive call features, allowing the service providers to offer these functions to their subscribers. Provided that the telephone sets at the end-users side support these functions, callers can take advantage of these convenient features. Configuration of individual phone connection is easy using the multi-language Interactive Voice Response (IVR) or the web-based user's interface. Shared Broadband Internet Connection/Integrated 4-Port Switch. The gateways provide a convenient router function to permit office users to share the Internet broadband line. With 4 integrated Ethernet ports, office computers can readily connect to these gateways and use their built-in NAT/DHCP server functions for automatic logon to the Internet.
